Abstract
The invention discloses a method for vortex cooling and fragrance keeping of cigarettes. A vortex channel is arranged before the cigarette smoke enters a cigarette filter tip; the vortex channel is communicated with the outside by a passage; the cigarette smoke is naturally cooled in the vortex channel and fully mixed with the outside air entering the vortex channel, and then the cigarette smoke is fully filtered by the filter tip. The method reduces the intake of cigarette tar, and keeps the proportion of the scented material and moisture in the cigarette, thus maintaining the advantage of comfortable taste of the cigarette.
Description
Technical field
The present invention relates to the production field of cigarette, especially relate to a kind of method and cigarette structure thereof of cigarette vortex temperature-reduction fragrance-protecting.
Background technology
Cigarette is divided into no cigarette with filter tip and cigarette with filter tip two big classes is arranged.What quantity was maximum in the cigarette with filter tip is the fine filter stick cigarette of vinegar.Along with the development that reduces the tar content in cigarette technology, adopt the ventilation dilution technology and add adsorbent, as adding activated carbon of sorbent, used widely industrial with the technology that increases filter effect.
Cigarette ventilation dilution technology is meant when sucking cigarette, in the process of cigarette smoke through the filter stick filtration, relies on the pre-punching that is arranged on the filter stick middle part to introduce air.This method can reduce the soakage of tar really, and still, owing to the internal drag reason of filter stick, air and cigarette smoke dilution more near the edge of filter stick enter the oral cavity, and filter stick center of circle part is because resistance is bigger, and the dilute strength of flue gas is lower.Also promptly, the tar that the filter stick edge filter falls is less, and the tar that the filter stick center of circle filters out is more, introduces the inhomogeneous of air and filtration, causes light partially, the phenomenons such as flue gas is dry, oral cavity discomfort of suction flavor of flue gas when sucking cigarette.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method of cigarette vortex temperature-reduction fragrance-protecting.This method had both reduced the suction of tar content in cigarette in sucking the cigarette process, keep the ratio of aroma substance and moisture in the flue gas again, to keep the comfortable taste degree of cigarette.
Another technical problem that the present invention will solve provides a kind of cigarette structure.
For solving above-mentioned first technical problem, the method of a kind of cigarette vortex temperature-reduction fragrance-protecting of the present invention, adopt following technical scheme: be before cigarette smoke is entering cigarette filter rod, swirl channel is set, this swirl channel passing hole channel and outside air communicate, cigarette smoke is cooling and fully mixing naturally in swirl channel, and cigarette smoke carries out complete filtration by cigarette filter rod then.
For solving above-mentioned second technical problem, a kind of cigarette structure of the present invention, it comprises, and cigarette props up, filter tip be connected that cigarette props up and filter-tip tipping paper; Prop up and place, slit, filter-tip joint portion at described cigarette, described connection cigarette props up with filter-tip tipping paper and is provided with at least one air duct.
Operation principle of the present invention is as follows:
The principle of general cigarette: from the mechanism that coke tar in cigarette produces, after cigarette was lighted, oxidation reaction took place in pipe tobacco and cigarette paper burning, and the organic fragrance matter of part takes place to decompose or combination reaction.The granule phase substance matter of burning back flue gas is held back and is filtered granule phase substance matter by unburned pipe tobacco, filter tip, becomes coke tar in cigarette after the flue gas granule phase substance matter that enters the oral cavity is removed moisture.From the variations in temperature of flue gas, cigarette burning district temperature is at 700-800 ℃, and in the cigarette smoking process, flue gas flows to filter end, and heat transferred residue cigarette props up and filter tip.Present cigarette paper has certain air permeability, and generally at 30-70cu, the intervention of mobile normal temperature air further reduces flue-gas temperature, and the flue-gas temperature that enters the oral cavity is generally about 30-40 ℃.Cigarette is in the process of burning and sucking, and along with the passing of burning point, the temperature that enters the oral cavity flue gas raises gradually, and in other words, the flue gas that burning produces is high more apart from oral cavity distance temperature far away more.
Principle of the present invention: cigarette prop up and filter tip between the joint portion have a natural slit, the width in slit is about 1mm, the slit of a 1～3mm also can initiatively be set, a plurality of air ducts that aperture, spacing equate or do not wait are set on the tipping paper at slit place.In the cigarette smoking process, outside air enters the joint portion that the slit between Cigarette and the filter tip forms by air duct, because air duct is all arranged around in the land, and the air drag of filter end is higher, so under the effect of air draught, flue gas forms eddy current, and flue gas is flowed by same direction and becomes disorderly flow regime.In the land, flue-gas temperature is owing to the intervention of air reduces, and the decomposition of part aroma substance is terminated, some granule phase substance matter are because the reduction of temperature, particle viscosity increases, and the enrichment of part small diameter particles becomes the bigger particle of diameter, helps being filtered mouth and holds back and adsorb.In the land, because eddy current effect, flue gas and air fully mix, but the ratio of moisture is kept in aroma substance and the flue gas, thereby the comfortable taste degree of cigarette is better.
The present invention has the suction that has both reduced tar content in cigarette, keeps the ratio of aroma substance and moisture in the flue gas again, with the advantage of the comfortable taste degree that keeps cigarette.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail
Fig. 1 is vertical cross-sectional schematic of a kind of cigarette of the present invention;
Fig. 2 props up and filter-tip joint portion partial schematic diagram for cigarette of the present invention.
The specific embodiment
Shown in Fig. 1,2, a kind of method of cigarette vortex temperature-reduction fragrance-protecting, be Cigarette and filter tip between, swirl channel is set, this swirl channel passing hole channel and outside air communicate, cigarette smoke is cooling and fully mixing naturally in swirl channel, and cigarette smoke carries out complete filtration by cigarette filter rod then.
A kind of cigarette structure, it comprises, and cigarette props up 1, filter tip 2 be connected that cigarette props up and filter-tip tipping paper 3; Prop up 1 and place, the slit, joint portion of filter tip 24 at described cigarette, described connection cigarette prop up 1 and the tipping paper 3 of filter tip 2 be provided with 6 apertures, the unequal air duct 5 of spacing.The place, slit, joint portion 4 of this structure is swirl channel just.
Cigarette sample to the fine filter stick cigarette of common vinegar of the cigarette (abbreviation sample) that adopts the vortex temperature-reduction technology and equal conditions (specification, prescription etc.) (abbreviation in the same old way) detects, from main flume assay and cigarette aesthetic quality assay, tar content in cigarette has reduced 2.42mg/ and has propped up, aesthetic quality's score with to remain basically stable in the same old way.
Conclusion sees the following form:
